Since I am using a bad camera, the very strange bluish grey color of this insulator refuses to show up accurately. This insulator has a small chip on the the base in the back, also perhaps a mere trace of wire groove rubbing that is very difficult to see but the glass is exceptionally clean, shinny, and has a crystal clear -like appearance in person. Of all the CD 143s I have, this is the only CD 143 that I have ever seen of this color in this crystal clear weird bluish grey color. I am asking $25 plus shipping with the standard rate of $8.10 for shipping.
